what should i do

I have this dude who I am cool with. I would say we are some what friends. Well we have been talking and chillin since spring time. He is very attractive kat. Some what my type. He has that masculine tall top swagger going on. He recently told me that he likes me and wants to kick it with me. I am so lost on what to do. Part of me says give him a chance and the other part says no just stay his friend. I had a list of pros and cons and they both weigh the same. God i am so attracted to him and he is just soft as pie sometimes. We are suppose to go out on friday night and see sup on this level. I just have all these expectations; bad things of course of things that could possible go wrong. I know i should think positive about the situation but things like this never seem to work out the way i want them to. Yeah i am making it all about me cuse yes part of it should. I have all these walls up that he says i should just let go and take down. But dealing with folks around here sometimes u have to put them up. He keeps telling me he wont hurt me but i just be like aight or un huh. He was dating someone for about a couple of months there and he kept pressing to be with me. He would say yeah i like him but it is u i want to be with. I would be like yeah right and play with him and he would get so mad at me. We are going on a date on friday. Just to see how it goes. I am gonna try to keep an open mind about this like he wants me to. But who knows. I'll keep ya updated.
